Artificial culture techniques of forest frog
At present, more and more people catch wild forest frogs, and the artificial excessive hunting and killing make the wild Chinese forest frogs less and less, and even face the danger of extinction. Forest frog and forest frog oil are more and more scarce, and the price is very expensive. Forest frog products have been in short supply in domestic and foreign markets. Some artificial breeding techniques of forest frogs are mainly introduced here.
Site selection of frog farm
Can be in front of the house, the yard to choose a flat ground to do frog farm, there should be groundwater, river, pool water, soil black soil, loess can be.
Construction of tadpole pond
In the frog farm, choose a place with flat terrain and easy drainage to build a tadpole pond. First of all, the ground of the place where the tadpole pool will be built will be piled with earth mat 15 / 20 cm high to facilitate drainage, then the earth around the pool will be piled into an earth dam, the height of the earth dam will be about 30 cm, and then the small pebbles and other sundries in the pool and on the earth dam will be sorted clean to prevent damage to the plastic sheet. spread two or three layers of sturdy plastic sheet on the tadpole pool, compact the four sides of the plastic sheet with soil, and put water on the plastic sheet. The water is 20-30 centimeters deep, so the tadpole pond is built. Of course, the width of the tadpole pond had better not exceed 2 meters, which helps to replace the dirty water in the pool. The size of the area depends on the number of frogs introduced. Generally, 100 pairs of frogs have a tadpole pond of 10 murals and 15 square meters.
Tadpole feeding
After hatching, the tadpole first eats the egg membrane that wraps the egg, and the egg membrane eats 7Mel for 10 days, and then begins to eat bait. Generally, 7 parts of corn flour and 3 parts of soybean powder are mixed with appropriate amount of water, cooked and fed to the tadpoles in a slightly dry shape. When feeding, put the bait directly into the water.
Feeding of young and adult frogs
After about 50 days of feeding, tadpoles become young frogs, land on shore, and become young frogs after eating insects, mosquitoes, yellow powder insects, maggots and so on. As long as the temperature is right, the frogs begin to catch insects. They are fed with small yellow powder worms or maggots every day, and the worms are scattered directly on the ground around the frog farm. In actual breeding, breeding yellow powder worms or fly maggots are generally used to feed young frogs and adult frogs, and yellow powder worms are bred with rice husks. Maggots can use 1 part of pig, cow, sheep blood (any kind) to add a small amount of rice husk or corn flour to outdoor vats, pots, cement ponds and soil ponds, and 3rel 5 days to naturally produce a large number of maggots, this method is simple and fast, fast, large quantity.
Construction of breeding ring of young frog and adult frog
During the period of breeding tadpoles, tadpoles can be raised directly in the sun. when tadpoles become young frogs, it is necessary to let young frogs grow in a sunshade and moisturizing environment, so it is necessary to build a culture circle for them. First, bamboo poles or pieces of bamboo can be used to build an arch shed with a height of 1.8 meters. The arch shed is covered by a sunshade net, and the bottom of the sunshade net is buried with soil to build a breeding circle of young frogs and adult frogs under the arch shed. To build a frog ring, you can build a large breeding ring or several breeding loops. after planning the size of the breeding ring, a wooden pile is buried every 2 meters around each breeding ring. The wooden pile is 1 meter high above the ground and is buried in the ground 20. 30 cm. Then use plastic sheeting to encircle all the wooden piles into a circle, the bottom edge of the plastic sheet is buried in the soil, and the top is rolled with a 2-meter-long wooden board and nailed to the top of the pile. Make the plastic sheet perpendicular to the ground, keep the upper edge of the plastic sheet parallel to the ground under the action of the plank, and form a right angle with the stake to prevent frogs from escaping. Tadpole ponds can be built in the breeding circle of young frogs and adult frogs, so that tadpoles can be fed directly after they become young frogs without changing places, saving time and effort, but do not cover the sunshade net on the arch when raising tadpoles. Wait until the tadpole becomes a young frog and then cover the sunshade net. Moisturizing means spraying water on the ground in the farm twice a day on a sunny day.
Extraction of forest frog oil
From the end of October to the end of November every year, the forest frog begins to catch a large female frog. In this season, the forest frog is obese, the oil is of good quality and the economic value is high. The forest frog oil is the ovary of the female frog, which is dried and extracted from the female frog. The captured female frogs were strung together from the nostrils of the frog's mouth with thin wire or string to dry for 10 days. Oil extraction method: the forest frog oil is taken out as a solid dry block, which is easy to store. There are many extraction methods of forest frog oil, generally using the dry forest frog to put the dried forest frog in hot water at 60mur70 degrees Celsius, soaking it for about 10 minutes, then take it out of the water and put it in a basin or other container, covered with moist sacks and other things, and put it in a warm room to moisten, about 10 MUE 15 hours, the whole forest frog can be stuffy and soft, and the skin and muscles can be softened, then the oil can be taken. When taking oil, one hand holds the soft forest frog, the abdomen is facing up, the thumb is tightly pressed against the two legs of the forest frog, and the other hand grabs the head of the forest frog and folds both hands down at the same time, then tear the skin close to the two legs to reveal flake oil, gently pry up one end with hands or razor blades, tear off two large pieces of oil, and at the same time take out sporadic small pieces of oil and put them on the plate to dry.
